A box contains some mangoes, apples and kiwis. 0.2 of the mangoes is equal to 80% of the apples. The number of kiwis is ⁵₆ of the total number of apples and mangoes. If there are 133 less apples than kiwis, how many fruits are there in the box altogether?

Mangoes	Apples	Kiwis
4x6	1x6
6x5		5x5
24 u	6 u	25 u

0.2 = ²₁₀= ¹₅
80% = ⁸⁰₁₀₀ = ⁴₅

0.2 of the mangoes is equal to 80% of the apples. Make the numerators the same.  LCM of 1 and 4 is 4.

1x45x4 of the mangoes = 4x15x1 of the apples
420 of the mangoes = 45 of the apples 

Mangoes : Apples
20 : 5 _(÷5)
4 : 1

The total number of mangoes and apples is repeated.  Make the total number of mangoes and apples the same.  LCM of 5 and 6 is 30.

Number of less apples than kiwis
= 25 u - 6 u
= 19 u

19 u = 133

1 u = 133 ÷ 19 = 7

Number of the fruits in the box altogether
= 24 u + 6 u + 25 u
= 55 u
= 55 x 7
= 385

Answer(s): 385
